To all whom t may concern:

Be it known that I, RUSSELL STYLns, a citizen of United States,residingat Brooku lyn, in the county of Kings and State of 6 New York,have invented new and useful Improvements in Burners, of which the following is a specification.

This invention relates to burners and more particularly to burners foruse in connec- '10 tion with gas heaters of the instantaneous typie.

he principal object of the invention is to provide a burner which willbe free from corrosion and which corrosion is now caused by the water f,condensation.

Another object of the'invention is the provision of a burner. includinga co per tube wherein a screeji usually employe in burners of this type,is insulated and 'supported in spaced relation to the sidewalls of thetube :for keeping the screen cool at all times whereby to eliminatebackfire.

A still further object of the invention is to provide a burner with a,burner head i'e- 26 movable from the burner and so constructed as toprevent the water of condensation from flowing into the flame openings.

A still further object of the-invention is to provide a burner whereinthe number of artsis reducedto a minimum thereby renering the same simle in construction, cheap of manufacture an highly eiiicient for thepurpose intended.

With these and other objects in view, the

a6 invention resides in certain novel construction and combination andarrangement of arts, the essential features of which are ereinafterfullv described, are particularly ointed out in the appended claims, andare illustrated in the accompanying drawing, in-

whichz- Fi re 1 is a vertical longitudinal sectona view through myimproved burner construction. i

46 Figure 2 is a horizontal sectional view on the line 2-2 of Fi re 1.

Figure 3 is a simi er view .of Figure 1.

Figure 4 er 59: Re errin more particularly to the drain ing,s the reerence numeral 10 desi tes'a copperi tube which is formed from' et stripon the line 3-3' is a detail view of the burner of material and the endsof which are wf vided with co-zicting portions 11, 11 w ich form a seamafter the strip has been formed into the tube 1.0. I [ind that by usingcop er as a burner tube, the Vcorrosion usuisly caused bythe water ofcondensation is e vented thereby adding greatly to the li e of the tube.This tube 10 is normally opened at both ends and adjacent the lower endthere is formed within the tube 10 a cement core 12, provided with aconical shaped bore 13 terminatin in a restricted portion 14. This core12 is ormed by inserting a mold in the lower end of the tube and pourinthe cement about the core and permitting it to dry. While the cement isin its softened condition, a suitable cylindrical screen 15 has itslower end anchored in the core 12 as at 16 whereby the same islsupported in vertical axial alignment with the conical shaped bore 13.By sup orting the screen \15 in this manner it w1ll)be seen that thesame is spaced from the side walls of the tube 10 and also insulatedtherefrom which serves to keep the screen cooled at all timesand preventback fire.

A burner head 17 is providedfor partially closin the up er end of the.tube and the same is forme with a pluralit of depending lugs 18 whichare adapte to frictionally engage the inner wall of the tube 10 forremovably securing the burner head thereto. The burner head 17 isfurther provided with an annular flange 19, the exteriorb wall of whichis beveled vas at 20.for cogaction with the inner walls of the screen 15whereby to also serve to retain the burner` head in place and to holdthe screen in vertical alignment with the axis of the tube. The burnerhead 17 is provided with a plurality of upturned li s 21 which co-'actwith one of theiopen en s of the tube 10 so as to provide flame(gpc/mugs 22 whereby to permit the fuel to. ow and be ignited. The endsof the lips 21 terminate 1n 'a downwardly turned ortion 23 which portionoverhan the ywel s of the tube so as to carry oif t e water ofcondensation thereby reventing the same from flowing into the ame openin22.

y e fuel Vsupply i 24 enters the lower end of the tube 10 agdies heldinaxial alignment therewith by means of a bracket 25,

. mixin to anythin said pipe 21 extending part way into the chamberwhich mixing chamber is define( by the bore 13.

In operation of the burner, the gas is introduoed into the mixingchamber by means of a pipe 24 and air sucked in through the lower end ofthe tube by reason of the restricted portion of the bore which portionsets up a vacuum for sucking in the air. This principle is practicallythe same as that used in the Bunsen burner and the air and gas afterbeing mixed in the chamber 24 passes up and out through the screen l5,the screen serving to break up the particles of mixture, after which thesame is ignited at the flame openings 22. It will be seen that with aburner of this construction, same will be free from corrosion as the coper cylinder will not corrode by reason o the water of condensationbeing carried off in the manner previously descrlbed.

While I have described what I deem to be the most desirable embodimentof my in-4 vention, it is obvious that many of the details may be variedwith out in any Way departing from the spirit of my invention andtherefore do not limit myself to the aXact details of constructionherein set forth nor less than the whole of my invention limited only bythe appended claims.
